Visualization and Emission Spectra of Flames in Combustion Chamber of Swirling-Oxidizer-Flow-Type Hybrid Rocket Engines

open access: yesJournal of Thermal Science and Technology, 2011
In order to clarify flame behavior in the combustion chamber of swirling-oxidizer-flow-type hybrid rocket engines, a small hybrid rocket engine with a large quartz glass window was fabricated to observe the inside of the combustion chamber from the front

Interface Engineering in Solid‐State Sodium Batteries: Advances in Materials Design, Interfacial Strategies, and Multiscale Characterization

open access: yesInterdisciplinary Materials, EarlyView.
Since solid‐state sodium batteries (SSSBs) are a promising solution for advancing sodium‐based energy storage, it is necessary to systematically summarize the development process of SSSBs. It focuses on the role of interface engineering in addressing challenges such as materials design, interfacial strategies, and multiscale characterization.

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Viability of an Electrically Driven Pump-Fed Hybrid Rocket for Small Launcher Upper Stages

open access: yesAerospace, 2019
An electrically driven pump-fed cycle for a hybrid rocket engine is proposed and compared to a simpler gas-pressurized feed system. A liquid-oxygen/paraffin-based fuel hybrid rocket engine which powers the third stage of a Vega-like launcher is ...

Low‐Velocity Impact Response of Nacre‐Inspired E‐Glass/Epoxy Composites With Varying Platelet Sizes

open access: yesPolymer Composites, EarlyView.
Impact response of nacre‐inspired E‐glass/epoxy composites with different platelet sizes. ABSTRACT This study explores the low‐velocity impact behavior of nacre‐inspired biomimetic platelet composites (NIBPC), using low‐cost E‐glass fiber in chopped strand mat (CSM) form as reinforcement and epoxy resin as the matrix.
